Answer:
180 ft^2
Step-by-step explanation:
Area of the rectangle is calculated by multplying : height*widht*lenght
15*6*2 = 180 ft^2
Answer: The mean is 49.
Step-by-step explanation:
First add up all the numbers.
48 + 51 + 48 + 48 + 50 = 245
Then divide 245 by the amount of numbers are in your data (there are five numbers).
245 ÷ 5 = 49
Answer:the first term is 6
Step-by-step explanation:
We would apply the formula for determining the sum of n terms of an arithmetic sequence. It is expressed as
Sn = n/2(a + l)
Where
n represents the number of terms in the arithmetic sequence.
l represents the last term in the arithmetic sequence.
a represents the first term in the arithmetic sequence.
From the information given,
l = 204
n = 12
Sn = 1260
We want to determine a. Therefore,
1260 = 12/2(a + 204)
1260 = 6(a + 204)
a + 204 = 1260/6 = 210
a = 210 - 204 = 6
Point Slope:
y-12=-3(x-6)
From there you can find the slope intercept form:
y-12=-3x+18
y=-3x+30
